“‘If your note is part of some George Clooney prank, as I very strongly suspect it is, you A-list amateurs are going to have to step it the f–k up,'” the comedians wrote. “We are not some easily confused starlets here. We are grown-ass, professional comedians. Please accept this fruit as a token of our sincerity. Best wishes, Elizabeth Tina Fey, Amy ‘Boston’ Poehler.”

Damon described Fey and Poehler’s hosting job as “great,” and noted that “everyone took a hit” from their jokes throughout the show — even him, who they called a “garbage man.”

One of the best jabs of the night, however, was one against “Gravity” star Clooney, a notorious celebrity bachelor.

Fey described Alfonso Cuarón’s space thriller as “the story of how George Clooney would rather float away into space and die than spend one more minute with a woman his own age.”

Damon did not tell Letterman exactly what Clooney wrote in his three-way revenge prank, but that’s okay, because Clooney did at a SiriusXM Town Hall event with the “Monuments Men” cast on Wednesday.

“I sent her a letter saying, Dear Tina, listen, it’s from Matt, and it just says, ‘Look, it sounds hypocritical because I laughed at the jokes about George and Leo, but you know, that’s sort of what people think about them. But when you called me a garbage man, it just seemed like low hanging fruit, it just seemed like an easy joke,” Clooney explained. “And you know, I don’t want an apology, I don’t want anything else, I just want you to know that my kid now calls me the garbage man.'”
